Merge tag 'ras_core_for_v5.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 RAS updates from Borislav Petkov: - Add the required information to the faked APEI-reported mem error so that the kernel properly attempts to offline the corresponding page, as it does for kernel-detected correctable errors. - Fix a typo in AMD's error descriptions. * tag 'ras_core_for_v5.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: EDAC/mce_amd: Fix typo "FIfo" -> "Fifo" x86/mce: Include a MCi_MISC value in faked mce logs x86/MCE/AMD, EDAC/mce_amd: Add new SMCA bank types
